An adjustable structure for a hand tool includes a handle, a shank connected with the handle, and an adjusting device mounted on the handle. The handle has a chamber defined therein and two protrusions extending therefrom. The shank has at least two clamping grooves annularly defined therein. The adjusting device includes a rotary element, two slidable elements and two springs. The rotary element has a through hole defined therein, such that the shank passes through the through hole. Two sliding channels are defined in the rotary element. Each sliding channel receives one slidable element and one spring. Each slidable element has a clamping surface formed thereon for engaging with the clamping groove. Each slidable element has an abutting slot defined therein and receiving the protrusion. The shank is adjustable by moving the desired clamping groove to selectively engage with the two slidable elements. |
